the azobenzene group based on the reversibility of hydrogen bond after the grating
formation (Zettsu et al. 2008).
As we have mentioned above, hydrogen-bonding could be used to introduce LC
property from amorphous molecules. Parallel to hydrogen-bonding, halogen-bonding, which is the noncovalent interaction between halogen atoms and neutral or
anionic Lewis bases, could achieve the same purpose (Metrangolo et al. 2005).
